Profile Summary

Welding has been the main focus of my research work though I have also worked on casting and crystal growth. These are important areas in materials processing. I have been teaching materials processing, welding metallurgy, and the joining of various engineering materials. My book Welding Metallurgy (2nd edition 2003) has contributed significantly to the science of welding and is widely used in research, industry and education. The 3rd edition will be in preparation soon.

Education

PhD (metallurgy) 1978, Massachusetts Institute of Technology

MS (materials engineering) 1974, University of Wisconsin

BS (chemical engineering) 1971, National Taiwan University

Research Interests

My research work has been on understanding and controlling cracking, segregation, microstructure and transport phenomena during welding, casting and crystal growth. Examples of my current interests include:

Welding of magnesium: Being the lightest structural metal, Mg can help reduce vehicle weight and hence improve fuel efficiency. We are interested in applying advanced gas-metal arc welding (GMAW or MIG) to overcome spattering. GMAW is a widely used process for Al but not yet for Mg.

Welding aluminum to steel: The automotive industry has been interested in dissimilar-metal welding. We are interested in applying advanced GMAW to improve the joint strength.

Welding of steels: P91 is a creep-resistant ferritic steel with improved performance at high temperatures and under higher pressures. Filler wires for welding P91 steel are needed.
